Anyone using Mirena IUD??

Donnette • Mon, Sep 15 2014 •

So I had a baby June 26, I had my IUD placed august 19 and I hadn't had a period since I stopped bleeding after giving birth. When I got my period after getting my IUD it has lasted 21 days now!! I called my gyn and she said that it is fairly normal and could possibly last up to 3 months. Has anyone had a similar experience?
